Brief summary
The purpose of this study is to evaluate the pharmacokinetics and relative bioavailability of Emtricitabine (FTC) and Tenofovir alafenamide (TAF) when administered as a fixed-dose combination (FDC) with darunavir (DRV) and cobicistat (COBI) (darunavir/cobicistat/emtricitabine/tenofovir alafenamide (D/C/F/TAF) relative to administration as an FDC with Elvitegravir (EVG) and COBI (Elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide), under fed conditions in healthy subjects (Panel 1); evaluate the single-dose pharmacokinetics and relative bioavailability of DRV, COBI, FTC and TAF when administered as an FDC (D/C/F/TAF) or as separate agents (D+C+FTC/TAF), under fed conditions in healthy subjects (Panel 2) and to evaluate the impact of food (fasting or high-fat breakfast) on the single-dose pharmacokinetics of DRV, COBI, FTC, and TAF when administered as an FDC (D/C/F/TAF) in healthy subjects (Panel 3).
Detailed description
This is a Phase 1, 3-panel, open-label, randomized, 2-way crossover study in healthy subjects. Healthy subjects will be divided over 3 panels (Panel 1, 2 and 3). Subjects will be randomized within each panel. In each panel, during 2 subsequent sessions, each subject will receive 2 treatments (Treatments A and B in Panel 1, Treatments C and D in Panel 2, and Treatments E and F in Panel 3). Each treatment is defined as follows: Treatment A: single oral dose of D/C/F/TAF 800/150/200/10 milligram (mg) as FDC tablet under fed conditions (standardized regular breakfast); Treatment B: single oral dose of E/C/F/TAF 150/150/200/10 mg as FDC tablet under fed conditions; Treatment C: single oral dose of D/C/F/TAF 800/150/200/10 mg as FDC tablet under fed conditions; Treatment D: single oral dose of DRV as 800-mg tablet, FTC/TAF as 200/10 mg tablet and COBI 150 mg tablet under fed conditions. Treatment E: single oral dose of D/C/F/TAF 800/150/200/10 mg as FDC tablet, under fasted condition and Treatment F: single oral dose of D/C/F/TAF 800/150/200/10 mg tablet, with a standardized high-fat breakfast. Each treatment will be separated by a washout period of at least 7 days. Primarily pharmacokinetic parameters will be assessed. Subjects' safety will be assessed throughout.

Inclusion criteria
* Subject must be a non-smoker for at least 3 months prior to selection * Subject must have a body mass index (BMI, weight in kg divided by the square of height in meters) of 18.5 to 30.0 kg/m\^2, extremes included * Subject must be healthy on the basis of physical examination, medical history, vital signs, and 12-lead ECG performed at screening. If the results are outside the normal reference ranges, the subject may be included only if they are not listed under the
Exclusion criteria
and if the Investigator judges the abnormalities or deviations from normal to be not clinically significant. This determination must be recorded in the subject's source documents and initialed by the Investigator * Subject must be healthy on the basis of clinical laboratory tests performed at screening. If the results of the biochemistry panel, hematology, or urinalysis are outside the normal reference ranges, the subject may be included only if the abnormalities or deviations from normal are not listed in the
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Maximum Observed Plasma Concentration (Cmax) of Darunavir (DRV), cobicistat (COBI), Emtricitabine (FTC) and Tenofovir Alafenamide (TAF) | Up to 72 Hours after study drug administration | The Cmax is the maximum observed plasma concentration. |
| Area Under the Plasma Concentration-Time Curve From Time Zero to Last Quantifiable Time (AUC [0-last]) of Darunavir (DRV), cobicistat (COBI), Emtricitabine (FTC) and Tenofovir Alafenamide (TAF) | Up to 72 Hours after study drug administration | The AUC (0-last) is the area under the plasma concentration-time curve from time zero to last quantifiable time. |
| Area Under the Plasma Concentration-Time Curve From Time Zero to Infinite Time (AUC[0-infinity]) of Darunavir (DRV), cobicistat (COBI), Emtricitabine (FTC) and Tenofovir Alafenamide (TAF) | Up to 72 Hours after study drug administration | The AUC (0-infinity) is the area under the plasma concentration-time curve from time zero to infinite time, calculated as the sum of AUC(last) and C(last)/lambda(z); wherein AUC(last) is area under the plasma concentration-time curve from time zero to last quantifiable time, C(last) is the last observed quantifiable concentration, and lambda(z) is elimination rate constant. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Number of Subjects with Adverse Events | From signing the Informed Consent Form (ICF) up to 10 days after last study drug administration | An adverse event is any untoward medical event that occurs in a participant administered an investigational product, and it does not necessarily indicate only events with clear causal relationship with the relevant investigational product. |
Other
| Measure | Time frame | Description |
|---|---|---|
| Time to Last Quantifiable Plasma Concentration (Tlast) of Darunavir (DRV), cobicistat (COBI), Emtricitabine (FTC) and Tenofovir Alafenamide (TAF) | Up to 72 Hours after study drug administration | The Tlast is the time to last observed quantifiable plasma concentration. |
| Time to Reach Maximum Observed Plasma Concentration (Tmax) of Darunavir (DRV), cobicistat (COBI), Emtricitabine (FTC) and Tenofovir Alafenamide (TAF) | Up to 72 Hours after study drug administration | The Tmax is defined as actual sampling time to reach maximum observed analyte concentration. |
